The card is easy to install thanks to the well-supplied card reader. Install the software (unfortunately only Windows and OS X, a Linux software would have made it even more beautiful). Thereafter, the account must be registered, and the software of the card be brought to stand (at the time of Rezesion 5.0018 Oct 30 2012). During the setup you already get a window which provides instructions for the different modes of the map. I operate in Direct mode on a Google Nexus 7 ". In addition I have set up the card in direct mode on the computer, and after that it was super easy. On the Nexus installed the software logged in, select the card and 123 went it going . (see also here for the steps: [...])
At the Canon 650D the Eye-Fi can be activated and deactivated via the menu of the camera menu (Menu> Kameraeinstellungen-> Eye-Fi). Furthermore, you can also check the status of the card to see if it is enabled. Please do not be irritated if the menu does not appear, as it only appears when the Eye-Fi is plugged. A new icon on the Status screen, which provides information about the wifi AktiviƤt the map appears. It also seems as if the map hotspot disabled if a long time there is no transmission (Wifi icon is grayed out). The possibility of explicit deactivation but you can use the SD card, the Eye-Fi energy saving as easy. Whether one's own camera fits the Eye-Fi, you can under [...] determine.
After what one reads on the negative Rezesionen, I can only recommend to see if the camera definitely support the card. If she has no support, it often seems to lead to problems, or additional power consumption. But otherwise, I can wholeheartedly recommend the card, and say that you gives me a lot of fun.
